Design Features

Custom zirconia ceramic shafts, also known as ceramic stepped shafts, locating pins, or ceramic plungers, are high-performance custom 

parts used in precision machinery and industrial equipment, especially suitable for demanding applications.

Multi-Step Design

These custom-designed zirconia ceramic cores feature a multi-step structure for precise mechanical positioning and hold. Each step is 

precisely machined to ensure a perfect fit with mechanical components.

High Fracture Toughness

With a fracture toughness up to 9 MPa^1/2, it remains intact under impact or pressure, making it particularly suitable for 

high-load applications.

Excellent Abrasion Resistance and Hardness

A Vickers hardness of 11.5 GPa ensures superior abrasion resistance and long-term stability under continuous mechanical action.

Excellent Thermal Stability

A thermal conductivity of 2.5 W/(m·K) and thermal shock stability of 250°C allow it to maintain performance in varying temperature 

environments.

Chemical Stability and Self-Lubricating Properties

The chemical inertness of zirconia allows it to be used in a variety of corrosive environments, while its self-lubricating properties reduce 

wear in dynamic applications.
